Any factor which decreases either cardiac output or peripheral vascularresistance diminishes systemic arterial pressure and hence cerebral perfusion. Placental vascularresistance was then calculated from steady state pressure and flow data. Nevertheless, severe pulmonary hypertension and elevated pulmonary vascularresistance were present. Oximetric studies were performed in six patients (one older and five younger patients) to determine the reversibility of an initially high pulmonary vascularresistance. Conversely, systemic vascularresistance did not change at all neither after loading with nitric oxide nor after combined administration of nitric oxide and beraprost. At all levels of inspired oxygen (1.00, 0.21 and 0.15), ventilation at a pressure of 15 cm of water increased pulmonary vascularresistance. The hemodynamic responses to each vasodilator were evaluated by calculating the percentage change in pulmonary vascularresistance, and the ratio of pulmonary-to-systemic resistance. All had lowered pulmonary vascularresistance or systolic pulmonary artery pressure compared to preoperative values. There were no correlations between the postoperative pulmonary artery size and the postoperative cardiac index, the pulmonary vascularresistance or the pulmonary artery pressure. If the pulmonary-to-systemic flow ratio is still too high, arterial carbon dioxide tension can be raised further to increase pulmonary vascularresistance. In both groups the pulmonary vascularresistance showed no significant change. These changes in pulmonary vascularresistance are shown for end-expiratory pressure levels of 0, 5, and 15 cm of water. Increased pulmonary vascularresistance in the dependent zone of the isolated dog lung caused by penvascular edema. With the onset of a decreased systemic vascularresistance of pregnancy, these fixed output states compensate poorly and symptoms of cardiac insufficiency are common. Using this technique, real-time changes in systemic vascularresistance, stroke volume and cardiac output can be non-invasively measured during orthostatic stress. The improvement of cardiac function in right heart failure was first demonstrated in adults with respiratory distress syndrome12 due to reduced pulmonary vascularresistance. As pulmonary vascularresistance falls, the regurgitant fraction will decrease accordingly, effectively reducing the volume load on the right ventricle. Inhaled nitric oxide improves gas exchange and lowers pulmonary vascularresistance in severe experimental hyaline membrane disease. As expected, both increasing positive end-expiratory pressure and decreasing fraction of inspired oxygen increased pulmonary artery pressure and pulmonary arterial vascularresistance. For those who responded to salt supplementation, the forearm vascularresistance also increased. These examples are from corpora and from sources on the web.
